Sub-code problem

[kiwiakl]

Can you please help, problem with buring PSX games using any kind of software. I have a HP 9500 writer and I have being trying to use Nero 5 and clonecd. The burn says successful and the same information is on the burned disk as original source disk.
But when trying to load cd on playstation with mod chip I only get as far as the white Playstation screen.
I have saved copy of log using Nero and information states that drive is unable to read subcode ?? does this sound correct

Please let me know your comments ?? much appreciated
